Renewed' September 4,1931. Y i V Book matches which are manufactured in continuous strips orbands and in which the single matches are held together by'a strip ofthe material, are very largely used at present. Experience shows that inpractical use,the' single matches are almost never completely detachedat their roots, but-break off a little higher, owing towhich the lengthof the match is reduced, and irregular bits are left in the book.

It has been already proposed, for the .pur-

poseof facilitating the tearing off of the matches,"to weaken theirconnection to the strip of material by means of a notch. This notchinghas not, however, led to the desired result as'it leaves: between thematch and the strip a b'ridge diflicult to break, in which the fibreslie very close together.

It is necessary to give the match, preferably V band, ortreated inauniform manner, preferably made before the beginning of the process ofmanufacture, a shape that would eliminate the drawbacks above referredto, and at the same timeenable strips or booksof mzuzohes to bemanufactured from one or more continuous bands in a. single operation.

In order always to ensure an easy breaking of]? of the matches at theroot, the junction of the matches to the strip could be weakened byremoving material atthat point. This is preferably doneby means ofperforations,

theobject of which is to provide the points oflleast resistance andthereby insure the breaking off of the matches just at thoseexactpoints, so that the whole of the length of the match can be utilized,and no pieces are left in the book; moreover, these perforations whichare made at the beginning of the process whichfinally results in theproduction offinished matches, constitute organs which, in cooperationwith a suitably arranged machine, alford a guarantee for a perfectmanufacture of finished match books or packets.

Incarrying-outthe process,the strip or a plurality of such bands to beof cardboard or the like,'are unwound from large reels or rolls andduring the various operations required for the manufacture of books ofmatches, are guided in a suitable manner so that on the one handthe feedor 'ner if they are open even wheels described later advance of the bandalways remains the same forgiven operatlons or, when treatingsimultaneously several strips of matches, or such strips and a band ofcardboard intended to of the single strips tothe extent of the width ofone book match. I

It is obvious that the said perforations (17) can fulfill their objectirrespectively of the point of the width of the match at which they areproduced. In vie-w however of what has been stated in the beginning,itappears advisable to provide these perforations at the root of thematches so thatthey produce a weakening at the jointbetween the matchesand their common holding strip (15), which weakening is of greatimportancefor the subsequent use ofthe matches.

The perforations provided at the root of the matches, will best fulfilltheir, object in subsequent use if they are arranged exactly betweeneach two matches, in such 'a manner that each cutseparating the matches,is of exactly the same length, as owing to the'perforations provided,the matches can be torn off in a neat manner. It must be pointed outhere that the perforations ,pIOVldeCl in the continuous band cannotfulfill their object of forming guide organs in a perfect man- 7 only atone side, as this affects the reliable guiding, by the pin on.- It istherefore inadvisable to remove a portion of the material between eachtwo matches, at the point Where the'separation cut is made, whether suchremoval be efiected throughout the whole struction similar to providedfor the guiding. Another drawback of any removal of material is alsothat the material is wasted, the cutting tools work in a morecomplicated manner, and a smaller number of matches can be producedduring the same operation. of the machine.

The general construction of a machine for the manufacture of strips ofmatches or of books of matches containing such strips, in a" singleoperation, may be for instance such that the support for therolls ofcardboard bands is adjoined bythe which cuts the single matches in thecardboard 'ban'ds. Then follows a araffinin device which if desired maybe combinedwith aniimpregnating device. A. setting device which nowfollows,bends the matches'alternately'to different sides and preparesthem for the clipping process which provides them withheads. After theband has been carried in long sinuous lines for the purpose of airdrying, a device could be provided which glues 'tggether two bands of'matches. carried one above the other,a1 1d at thesame time these twosuperposed bands can be brought to another cardboard band intended toform lIllQCOVQI. By means of a cutting device can then be producedsections or cuts, corresponding to t e width of the match book, namelyin such a manner that the strips of matches which are now superposed,and the band supplying the cover, are cut simultaneously. The manner inwhich the match books are finished, is immaterialfor the invention. 1

It isc'lea-r that such a' machine, of a conthat just described by way ofexample, could work correctly only provided that the feed devicesarranged between the single working devices give a perfectly regulatedorpositive advance, as is the case when gear wheels are used, but not whenfriction wheels are used. Tlhiscan beobtained with exactness if, theperforations made in the cardboard band or hands are themselves arrangedat a uniform distance apart. The pin wheels or the like engaging withthese perforations, must then necessarily give an advance correspondingexactly to the distance between two such holes, that is to say to thewidth of one match.

In the accompanying drawings isdiagrammatic-ally shown a device forcarrying out the process ofthe invention. Figs. 1 and 2 represent inside view and elevation the varioustools efiecting the perforations andcuts, in their places relatively to analready finished strip. Fig. 3represents perspectively the junction of four strips, and Fig. l shows acard of matches manufactured by the process according to tire presentinvention. Figs. 5 and 6 show the setting device infront and side view.Fig. 7 shows a spring-controlled pin of the setting-device.

The manner in which the said holes or perpun-ch-ing device forations areto be produced, in diagrammatically illustrated by way of example inFigures 1 and 2. To a press plate 1 vertic.lly adjustable for instanceby means of eccentrics not shown, is secured a plate 2 with parallelcutters 3 and further a plate 4 with perforating puIJS hBS 5, setting-vmandrels 6, a wide punch 7 and head cutters 8. A table 9 carries a plate10 as counter-plate for th'ecutters 3, as well as 'a plate ll withholesfor the guiding of the punches 5, 7 and 8. Moreover, to the press platelis secured" an ejectordevice 12 which ejects the completely cutouttongues through a slot 13 of the table top.

On reaching the punchingdevice, a cardboardband a is provided betweenthe plates 2 and;10 by thecu-tters 3 Withparallel cuts which do notextend quite to tl e edge of the cardboardbands, so that ateach-longitudinal edge there will still be left a holdingstrip 1a or 15.After a further advance-of'the cardboard band or; bands, duringthepassage between the platese and 11, the cutters '8 cut out at onelongitudinal side of the band the ends 1430f the. tongues subsequentlycarrying the match heads, an d at. the same time-the punches ,5 punchat; the rooftof the matches .30 holes- L7; in the-holdenstrip 15;, andthe wide punch 7 punches out. an elongated hole 18, :Each-twoofsuch'elongated holes 18cmclose a. st rip of matches intended foramatch book.

Any slightmovement of the band that: maybenecessariy can beie'ffected by, thesetting. mandrels 6,. as the band: is, not held fast before the punchingdevicebecomes operative, but is merely laterally guided.

The holes 17 providedin the described manner at proper intervals, :areutiliZed during the who-le' subsequent working operation for theguiding andadvancingof the band a,

owing to the -.engagement"with the saidhole's of pinsiof pin wheels orthelike.

Theqnanner inwvhichthese holes are utilizedfor the guiding, isillustrated in-perspect ve in Figure by Way of example for-thesimultaneous guiding; of: four match bands which are to 'be guided'together with: a band intendedto form the bookcover. Each two strips. wand]; .or all and bl-arefa-rranged'here sideby side, whilst the stripsaand'b; or 'b and (U are situatedvabove each other, The

eagues two upper match strips a and I) pass overan upper pin wheel 19,and the lower match strips a1, 51 pass over a lower pin wheel 20.

The pin wheels 19, are of exactly the same construction and make thesame movement, so that the pins of the wheels 19, 20

engage exactly with the holes 17 of the match strips, and all the matchstrips, (2, 6, a1, 61, are moved in a perfectly uniform manner. Theholes 17 of the upper bands a, I) always coincide therefore exactly withthe holes 17 of the lower bands a1, 61, and the bands can therefore befor instance glued together exactly hole and hole. The gluedtogetherdouble match strips a, a1 and 6, 61 which travel next to eachother, can further be connected, in amanner which need not be furtherdescribed here, to a cover band 21 which is provided with advance holes22 arranged at distance apart which correspond exactly tothe width of a.single match book. A feed roller 23 of the cover band 21 carries on thecircumference pins 24, the distance between which corresponds to thedistance between the holes 22, or to the width of a match book. The pins24 of the adjustable roller 23 during its ro-' tation, engage with theholes 22 of the cover band 21, and thus bring about always an exact anduniform advance of the cover band. As the match strips are moved in themanner already described by the pin wheels 19 and 20, the pins of whichengage with the series of holes 17 of the match strips, the correctposition of the match strips on the cover band 21 is ensured providedthat the drives for the pin wheels 19 and 20 and for the roller 23 areproperly connected together, so that this also ensures that during thesubsequent cutting of the strips into books, the cuts will always beeffected at the proper place.

For the part of the machine just described, the guiding by holes andpins is required wherever it is a question of exact cooperation of toolswith portions of the match strips to be treated. Only by way of examplemay be mentioned the setting device which is intended for bending thematches, before their dipping, alternately to opposite sides. The stripis moved above a receptacle 25 filled with the impregnating mass'for thetops of the matches between two wheels 26 tudinal direction. In eachwheel there are provided spring controlled pins (27) near the edge ofthese wheels. pins pressed by thesprings 31, project over the side wallsof the wheels. On the frame there is mounted a cam 32 upon which run thetops 28 of the spring controlled pins 27 while the corresponding wheelturns so that the spring-controlled pins are displaced in the wheel 26;the cam 32 rises obliquely from the right edge I to the edge II, then itdoes not alter its place up to the edge III and falls obliquely to theedge IV. Therefore the cam 32 has a trapezoid-like cross section. The

The setting device is followed by a feedconsisting of a sprocket wheel'33,the"pins of which engage with the 'holes 17-of the strips, in orderto insure a perfectly regulated advance of the strip, so that thespring-controlled pins engage the matches exactly at" the-proper place.

For the purpose of'exact guiding of the matchfstrips during the variousworking operations of the machine, it is in itself immaterial at whichportion of the width of the bands the holes or'perforations 17 areprovided. It is preferable however to arrange these perforations in themanner illustrated,

at the root of the matches, namely-in such a manner that theperforations are always situated between each two matches. As alreadystated, this provides the weakening of the joints of the matches to theholder part 15,,

facilitating the tearing olf of the single matches from the said holder,as points of least resistance are producedat'the root of the matches, sothat the separation takes place easily and always at the root, owing towhich the matches broken off, always have the same length, and noirregular bits are left in the book cover.

A card or strip of matches manufactured by the process described, isshown in Figure 4.

The single matches separated from each other by cuts, are attached attheir bottom end to anarrow strip 15 of the material, of which they aremade, and between each two matches 30, immediately above the root, isarranged a series of holes 17 in such a manner that they are situatedbetween each two matches 30. Owing .to the provision of these holes 17,places of least resistance are produced at the root of the singlematches, where they can be broken off. The perforations 17 can have anydesired shape, but the round shape has proved best. The processdescribed can be applied to any materials suitable for the manufactureof such matches, such as flat wood plates, cardboard, and the like.
